just took my cylinder head and cylinder off my cr, was gonna have it bored, geuss i should have read the manuel first...it says, 87 cr 250r models cannot be rebored because of the nikasil-plated cylinder.says if there is wear the whole cylinder has to be replaced. i have not measured it yet to check for excesive wear. i'll replace the rings either way i geuss, if it is too wore it's not even worth having i think. oh well. my buddy was supposed to buy it, but i dont know now? we'll see.
